Exolit® OP 945 (TP)

Finer grained version of aluminium diethyl phosphinate flame retardant for adhesives, films and fibres

Edition Date :
September 17, 2019

Exolit OP 945 (TP) is a white, fine-grained powder based on an organic phosphinate with a D95 of less than 5 µm. The product is not hygroscopic and it is insoluble in water and common organic solvents like acetone, dichloromethane, MEK, toluene. Exolit OP 945 (TP) can easily be dispersed in solvents like acetone or MEK.

For more details see our Innovation Spotlight video.

Benefits
  • Based on an organic metal phosphinate
  • Not hygroscopic, insoluble in water and common organic solvents like acetone, dichloromethane, MEK, toluene
  • Good hydrolysis resistance
  • Halogen-free flame retardant with a high phosphorus content which is suitable for use in both thermoplastic and thermoset applications to meet the most stringent fire retardancy standards
  • Particularly suitable for very thin adhesive applications like flexible printed circuit boards due to its specifically designed particle size distribution; can be readily dispersed in epoxy resin systems when a high shear mixer is used
  • Low smoke toxicity
  • Non-halogenated flame retardant with favorable environmental and health profile
Further safety data and handling information is available from our current Material Safety Data Sheet. For disposal in accordance with the regulations the product should be treated as special waste and taken to a suitable incineration plant.
